INDEX.

SPECIFICATION forming part of Letters Patent No. 265,717, dated October10, 1882,

Applicationfiled May 12, 1832.

.To atl whom it may concern:

Be it known that I, LEWIS B. TEBBET'rs, of St. Louis, Missouri, havemade a new and useful Improvement in Indexes, ot' which the following isa full, clear, and exact description, reference being had to the annexeddrawing, making part ot' this specification, in which the improved indexis shown in perspective, the index being opened.

The present invention is an improvement in that class ot' indexeswherein names and reference-numbers appear in combination-a let-Ier-book index, for example.

The prominent feature of the improvement is arranging the numbers at thelett of or underneath the names, rather than at the right ot' and inline with the names, as heretofore has been customary-that is, the pagesof the index are ruled to form vertical columns to receive thereference-numbers and to form spaces to receive the names, the latterbeing at the right ot or above the line dividing the names and numbers,and the numbers being entered in vertical columns respectively beneaththe names to which they belong, as understood' more readily by referringto the drawing, where- K represents an index having the improvement,and, saving which, being ot' the usual construction.

L M represent pages of the index, the pagel L being intended tor namesbeginning, say, with the letter C and the page M with names beginningwith the letter D. 'Ihe pages are each ruled to form vertical columns NN N and the horizontal spaces O C C, and are also divided into spaces I)and Q, the space P being for the names and the space Qfor the numbers.The division between the spaces P Q may be suitably indicated, andpreferably by means of a series ot' the initial letters of thenames-that is, upon the page L a series of the letter C appears and uponthe page M a series of the letter D, and so on. The series is arrangeddiagonally upon the page, so far as is practicablethat is, from theupper lefthand corner of the page diagonally across the (No model.)

page to the point R, at which point the space between the initials andthe righthand side of the page becomes too short to be narrowed anymore. Accordingly, to utilize the space S of the page the series fromthe point R extends vertically downward, and in this lastnamed space thenames and numbers are entered in the usual manner, the numbers being Lat the right of the names. 'I is similarly utilized.

To illustrate the working of the improvement various names are enteredin the index, as in practice-tor.instance, the names Chase dt Co., Cabotdt Bro, Clay da Son, on the page L, and the names Deere 85 Co.,77 DayBros, Davis da Co.,77 on the page M. The reference-numbers 5, ll, 36,for Chase 85 0o., are entered in the column under the initial ot' Chasevl 00., the reference-numbers 9,413,115, for Cabot dt Bio, under theinitial ot' Cabot & Bro, and so on. The ret'- erence-numbers 325, 340,436, for Deere & Co.,77 are similarly entered in the column under theinitial ot' Deere d? (10., the numbers 361, 367, 600,v for Day Bros,under the initial of Day Bros, and soon. -ln the space S the numbers forClark St Co.7 are entered at the right of the name, and in the space 'Ithe numbers for Cass & Co.77 are entered at the right of the name.

The chief advantage ot' the improvement grows out of the fact that inreferring to the index it is easierto go through the referencenumberswhen arranged vertically in columns than when arranged horizontally atthe level ot' the names.

l claim- An index the pages ot' which have the initials of' the names piintcd diagonally upon the pages, and being ruled to form vertical spacesto enable the reference-num ber to be entered in columns respectivelybeneath said initials.

The corner-space LEWIS B. TEBBETTS.
